RVT ARDMS TEST PAPER QUESTIONS AND
SOLUTIONS COMPLETE REVIEW MATERIAL
●● If you detect flow toward the transducer in the right ACA while
using the temporal window,
Answer: there is probably an occlusion of the right ICA
●● Wernicke's aphasia
Answer: Inability to understand speech, speak, or follow orders
●● Boca Aphasia
Answer: Inability to speak, but can follow orders
●● What velocities are used when calculating ICA/CCA PSV ratio
Answer: Distal CCA PSV, and the ICA PSV that is the highest velocity
●● What is the most accurate way to measure diameter and area stenosis
in the carotid arteries?
Answer: TRV on US
●● Pt presenting for Carotid US: has history of MI, and a left ventricular
assist device is present. What is expected flow pattern in the NL CCA of
this patient?
, Answer: Low velocity, delayed upstroke, loss of pulsatility
●● if an acute left ICA occlusion is present, what will happen to the left
opthalmic artery:
Answer: it will demonstrate decreased or absent flow
●● The string flow sign is associated with which diagnoses?
Answer: Critical ICA stenosis
●● Bilateral homonymous hemianopia is most commonly seen with:
Answer: vertebrobasilar disease
●● TIA lasts for
Answer: less than 24 hours (stroke symptoms)
●● Standard TCD protocol for vasospasm
Answer: -perform serial exams to evaluate flow velocity in MCA
-report all MFV in MCA that are >120cm/s
-calculate lindegaard ratio
●● What vessels are commonly affected by fibromuscular dysplasia?
Answer: Carotid
